VII. INSPECTION AND REJECTION. 



15. Inspection. The inspector representing the purchaser shall have free entry, at all times 

 while work on the contract of the purchaser is being performed, to all parts of the manufacturer's 

 works which concern the manufacture of the material ordered. The manufacturer shall afford 

 the inspector, free of cost, all reasonable facilities to satisfy him that the material is being furnished 

 in accordance with these specifications. All tests (except check analyses) and inspection shall be 

 made at the place of manufacture prior to shipment, unless otherwise specified, and shall be so 

 conducted as not to interfere unnecessarily with the operation of the works. 



1 6. Rejection, (a) Unless otherwise specified, any rejection based on tests made in accord- 

 ance with Section 5 shall be reported within five working days from the receipt of samples. 



(b) Material which shows injurious defects subsequent to its acceptance at the manufacturer's 

 works will be rejected, and the manufacturer shall be notified. 



17. Rehearing. Samples tested in accordance with Section 5, which represent rejected 

 material, shall be preserved for two weeks from the date of the test report. In case of dissatis- 

 faction with the results of the tests, the manufacturer may make claim for a rehearing within that 

 time.
